Not ideal though, I still need a way to initiate PPP from a Windoze client without telnetting in and running my script...
Set up ip_masq'ing/nat, demand dialing with pppd and start/stop pppd from a crontab, configure windows to use the nix box as a dns and gateway.
Or use the bodge I do, I have PPP set to redial if the link fails, all I do is when I want to disconnect, I pull the power lead out the modem, when I want to reconnect I plug it back in again. Piece of piss :-)
Crude but effective (me in a nutshell) :-)
